... man, I'd have a lot of fun with that if
you can pull it off.
Heh, I like the way you say that .....

at least it's honest!
---steaming pile of meadow muffin--- yeah, I'm lucky all right. But I have to move all my stuff to Thailand soon to be with my arcade habit-supportive partner .... and I can see that everyone will start bleeding from the heart for me now after I said that (NOT!).
Is this a sit-down or standup?
It's an upright, by circumstance rather than design.
By another lucky break, I just happenned across a matching (for my cab) control panel w/ 270 wheel & high-low gear shifter when I was picking up something else. the CP was just sitting out in front of his garage with some lesser arcade ---steaming pile of meadow muffin---. I asked him about it and he said I could have it for free, he was waiting for a scrap merchant to pick it up and take it away. He said it was "too much hassle" to fit this kind of CP to a mame cab, and said to use a USB PC wheel instead. But I disagree.
Anyway, I have it now. I've tested it and the only thing wrong is that the potentiometer is stuffed. Probably why it was pulled off in the first place. So I bought a better one for about $2. Just going to order an A-PAC from Andy and get going.
For pedals I will use a set of old PC ones I picked up from the recycling place - they also have pots in them, so I can simply connect them to the APAC too (it will take up to 4 pots). When not in use they can be stashed out of the way. I'll also be able to easily pull the CP with wheel off and replace it with a conventional CP with joystick & buttons (which I already have at hand, of course!).
Still, starting to think about that idea of a 3 * 29" CRT driving setup - it wouldn't need to be a cab, just a driving seat and pop the monitors onto table-tops ...... you wouldn't make a cab, you'd make a small room ....
